  SAP Error Message WT124
  Message Text:
  
  Replenishment currently being run for customer &1 by user &2
  
  Cause
  This message occurs when a replenishment process (such as warehouse replenishment or stock transfer) is already running for the specified customer (&1) and is being executed by another user (&2). SAP prevents multiple simultaneous replenishment runs for the same customer to avoid conflicts, data inconsistencies, or duplicate processing.
  In other words, the system detects that a replenishment job is currently active and locks further attempts to start another replenishment for the same customer until the first process completes or is terminated.
  
  When does it occur?
  
  When you try to start a replenishment run (e.g., via transaction codes like LT24, LT21, or custom replenishment programs) for a customer or warehouse that already has an active replenishment process.
  When the previous replenishment process did not finish properly or is still running in the background.
  When a user forgot to release or terminate a replenishment run.
  
  
  Solution / How to resolve
  
  
  Check if the replenishment process is still running:
  
  Verify if the user (&2) mentioned in the message is currently running the replenishment.
  You can check active jobs or sessions in SAP using transaction SM37 (Job Monitoring) or SM50/SM66 (Work Process Overview).
  If the job is still running, wait for it to complete.
  
  
  
  If the process is stuck or did not finish properly:
  
  Contact the user (&2) to confirm if they are still running the replenishment.
  If the process is stuck or the user is no longer active, you may need to:
  
  Cancel or terminate the stuck job via SM37 or SM50.
  Clear any locks related to the replenishment process using transaction SM12 (Lock Entries). Look for locks related to replenishment or the customer number and delete them carefully.
  
  
  
  
  
  Restart the replenishment:
  
  After ensuring no active replenishment process is running and locks are cleared, try to start the replenishment again.
  
  
  
  Preventive measures:
  
  Train users to properly finish or cancel replenishment runs.
  Monitor replenishment jobs regularly.
  Implement checks or alerts for stuck or long-running replenishment processes.
